AdBlue®/DEF Tank
IMPORTANT:
Dirt/dust, oil, greases, detergents and any chemicals
and natural products must be prevented from entering
the Adblue/DEF tank.
The system will be damaged if dust or dirt enters the
tank clogging the filters in the dosing system.
Keep the tank clean at all times.
®
AdBlue /DEF is stored in a separate tank.
There is a fitting in the tank that comprises a heating
coil (2), a filter (3) and a quality sensor (4). The filter on
the suction line prevents any particles from circulating
through the system and causing disruptions. The filter
must be checked and cleaned as necessary.
There is a drain plug (5) on the bottom of the tank so
that the solution can be emptied when necessary, e.g.
for cleaning. The tank is fitted with a breather to
equalize pressure changes.
The filler pipe (1) is equipped with a blue cap to prevent
confusion when filling.
Tank level
The solution consumption varies during operations.
The level in the tank is shown on the gauge as a
percentage of the total tank volume.
When the level in the tank falls below the set limit, the
level sensor in the tank transmits a signal that stops
AdBlue/DEF dosing. A fault code is set in the engine
control unit, a warning lamp lights up and a fault
message is shown on the control panel. If solution is
not added, injection into the exhaust pipe will cease
and engine torque and engine speed will be limited.
When solution is added the fault message is canceled
and the engine is able to revert to full power. Refer to
EATS Inducements, page 50 for further information.
Should the tank become empty during operations this
will not lead to damage to the engine or the EATS
system, as the remaining solution will circulate and
cool the system. However, emissions from the engine
will increase as the injection valve is closed and no
exhaust aftertreatment will take place.
